[Task] Support configurable TLS #30
Description
Problem Statement
We should support configurable TLS per stream. This will help with wrapping this SDK with other SDKs and ease local testing.
Proposed Solution
Introduce a strattegy-like pattern class (TlsConfig) which knows how to configure a gRPC stream in terms of TLS.
Additional Context
How this was done in zerobus-sdk-py: Add TlsConfig class for strategy pattern configuration of TLS.
